Phytoplankton chlorophyll-breakdown pathway: Implication in ecosystem assessment
(2020)
The chlorophyll-breakdown to pheophorbide is determined by biotic factors such as grazing (via chlorophyllide) or senescence (via pheophytin). So far, much of the information on chlorophyll-breakdown is available from ...
Simulation experiments to elucidate variable fluorescence as a potential proxy for bulk microalgal viability from natural water, sediments and biofilms: Implication in ships ballast water management
(Elsevier, 2018)
The variable fluorescence fluorometry measuring microalgal biomass (initial fluorescence - F0, a chl-a proxy) and photosynthetic efficiency (Fv/Fm) has been suggested as a potential tool in ballast-water assessment. In ...
Effect of ageing on survival of benthic diatom propagules
(Elsevier, 2007)
A comparison of viable benthic diatom propagules based on the observations recorded immediately and after 5 years of ageing at 5oC is presented. The number of viable benthic diatom propagules decreased with ageing. However, ...
Distribution and abundance of benthic macroorganisms in and around Visakhapatnam Harbour on the east coast of India
(Marine Biological Association of the United Kingdom, 2015)
Benthic communities form an important component of the marine food chain. Their occurrence also provides information on the health of the ecosystem. A study was carried out to understand the distribution and abundance of ...
Influence of food concentration, temperature and salinity on the larval development of Balanus amphitrite
(Springer, 1996)
Influence of food concentration (0.5, 1 and 2 x 10 sup(5) cell ml sup(-1) of Skeletonema costatum), temperature (20 and 30 degrees C) and salinity (15, 25 and 35 ppt) on the larval development of Balanus amphitrite ...
Exploration and metamorphosis in Balanus amphitrite Darwin (Cirripedia ; Thoracica) cyprids: significance of sugars and adult extract
(Elsevier, 2002)
Earlier observations have shown that sugars in solution adsorb electrostatically through –OH groups to polar groups associated with the cypris larva temporary adhesive (CTA). Lens culinaris agglutinin (LCA)-binding sugar ...
Benthic dinoflagellate blooms in tropical intertidal rock pools: Elucidation of photoprotection mechanisms
(Springer, 2017)
Intertidal rockpools (RPs), forming a ubiquitous component of rocky shores, are biologically rich ecosystems influenced by short-term (hours-days) and long-term (days-seasons) fluctuating environments. So far, studies on ...
Settlement of non-native Watersipora subtorquata (DeOrbigny, 1852) in artificial collectors deployed in Colombo Port, Sri Lanka
(Regional Euro-Asian Biological Invasions Centre - REABIC, Helsinki, Finland, 2018)
Sri Lanka has been a key node in the historical maritime �silk route� since the 14th century. Colombo Port, with its strategic location in the Indian Ocean, handles most of the country�s foreign cargo. With increased foreign ...
Tiniest primary producers in the marine environment: An appraisal from the context of waters around India
(Current Science Association, 2011)
Phytoplankton (0.2 mm - 2 mm) are the major primary producers in the marine environment thereby forming a basic link in the marine food web. They are categorized into different groups depending on their size range. Cells ...
Difficulties in obtaining representative samples for compliance with the Ballast Water Management Convention
(Elsevier, 2013)
As implementation of the Ballast Water Convention draws nearer a major challenge is the development of protocols which accurately assess compliance with the D-2 Standard. Many factors affect the accuracy of assessment: ...
